O/S
Information on this block such as the block tag, DD
revision, and execution time
The revision level of the static data of the DI block. The
value of this parameter is incremented each time a static
parameter value is changed.
The user description of the intended application of the
block
Used by an upper-level system to identify grouping of the
block. Not checked or processed by the block.
The identification number of the plant unit. This
information may be used in the host for sorting alarms.
The actual, target, permitted, and normal modes of the
block
Indicates the error statuses related to the block itself.
The primary discrete value (or process value) for
execution of the block’s functions.
Indicates the value and status of block’s output.
Allows use of values manually set instead of the limit
switch input from the transducer block. When Disable is
set for this value, the block reflects the actual input value
and status. 1 = Disabled, 2 = Active
Not used in a AV550G.
Not used in a AV550G.
Option to control access from the host computer and local
control panel to tuning and alarm parameters. Before
write access to a parameter, set the GRANT bit in this
parameter to have the operation right to be granted. Then
after write access, check the DENY bit in this parameter.
If the write access is complete successfully, it is not ON.
Sets the block input/output options.
Defines block actions depending on block status
conditions. For DI blocks of a AV550G, only bit 0 (Invert:
on/off state inversion) is effective.
The channel number of the transducer block’s logical
hardware channel connected to this block. This parameter
is always fixed for the DI block of the AV550G.
Sets the time constant of damping for PV_D.
The status of the limit switch signal transferred from the
transducer block
Shows the contents of an update event (a change to the
setpoint) upon occurrence.
Shows the contents of a block alarm upon occurrence.
Indicates the current alarm statuses.
Selects whether alarms associated with the block will be
automatically acknowledged.
Sets the alarm priority level.
Indicates the status of the input for the discrete alarm.
Indicates the status related to the discrete alarm.
